Product Details

The Four Seasons Fan Clutch line focuses on replacement cooling components for vehicles that rely on precise fan engagement to manage engine temperature. Part number 36933 uses a thermal severe-duty design with a 6.45-inch maximum diameter, 3.25-inch fan bolt circle, 1.44-inch mount diameter, and 1.25-inch distance from clutch to mounting flange. It is a new, non-electronic clutch with reverse rotation and a hex mounting style, built for applications that call for a thread-on fan clutch and heavy-duty cooling performance. This part cross-references Monroe Shocks & Struts 272307 for the same application.

Common Problems It Can Address
